> I have tried emailing the Google Maps team to plead my case, but my correspondence went unanswered.

Where did they write?

How many times did they write?

How long ago did they write?

Did they try any other means of contact?

Did they try to go through, as only one example, linkedin and find someone that way (or any other way of researching a party that might be willing to help)?

It's unclear the effort that was put in here. Maybe it was maybe it wasn't. We don't have enough detail. Simply saying "my correspondance went unanswered" as much as we may think Google doesn't care doesn't prove that point.

I actually from time to time write to companies to try and sell them things. I put in effort and it appears that that greatly increases the chance that they will buy what I am trying to sell to them (meaning a decision maker not a clerk or the person who sorts thorough the spam). And email more than one time for that matter. And if it's really important try a phone call.
